7 Claims.

This invention relates to sewing machines, and more particularly totable top constructions for drop head sewing machines.

1 My invention is shown herein as embodied in an automatic lift typemachine, i. e. one in which the head frame is connected with the lid insuch manner that the manual moving of the lid automatically raises thehead frame into operative position or lowers it into the drop headcabinet. However, the invention may be embodied in drop head sewingmachines without the automatic lift feature.

Usually the table tops of drop head sewing machine stands are providedwith lids for covering the opening produced by the lowering of the head.Such a lid also functions to support the work when the head is in raisedor operative position. Heretofore the lid has been hinged at one end toa side margin of the table top or the top has been provided with araised member of less length than the top and the lid hinged to a sidemargin of the said raised member. In the first mentioned construction(with lid hinged to table top edge) in order to be symmetrical when thelid is on the table top, the lid must be as long as the table top. In afull width machine this is objectionable when the machine is in usebecause of the space the extended top thus occupies, and is furtherobjectionable because of the cost and the lack of support for the lidwhen extending outwardly from the table top edge. The second type (lidhinged to intermediate raised member) provides better support for thelid than the first, and the lid need not be as long as the table top,but this construction requires the use of a raised member as large asthe lid, intermediate the lid and table top when the machine is closed,towhich the lid is hinged,the top of the said raised member being flushwith the lid when the latter is resting on the table top and extendingbeyond the same.

The main object of this invention is to obviate the objections hereindescribed and to provide means for hinging a lid directly to the tabletop but inwardly of the end edge in such manner that the lid will beflush with the table top when the machine is in use and will restdirectly on said table top when the machine is not in use.

Other objects and advantages will be apparent from the followingspecification.

Fig. '7 is a View similar to Fig. 6 showing the parts in differentpositions.

Fig. 8 shows the parts illustrated in Figs. 6 and '7 in still anotherposition.

In that embodiment of my invention which I have chosen to illustrate inthe drawings, a drop head sewing machine cabinet is indicated as a wholeat it]. It is supported by legs II, secured to the inner walls [2 of thecabinet by screws 13.

The table top is rectangular in shape when the machine is closed asshown in Fig. 4. The top comprises a fiat table member I4, fixed to thecabinet iii, and cut away at one end to form a rectangular recessbetween the parts l5, of the topl4. A top section [6, also rectangularin shape and of a size to occupy said recess when the cabinet is closed,is hinged to the cabinet wall I! by hinges l8. The plates of the hingesl8 are countersunk in the outer edge of the upper surface of the cabinetwall H and lower surface of the top section It so that said top memberl6 fits properly in the recess of the top l4 when in the positions shownin Figs. 4 and 8. The top' I4 is also provided with a centrally locatedopening l9, rectangular in shape, in which is mounted the head framesupporting the sewing head 2i. The head frame 20 is hingedly connectedto the top I 4 by hinges 2| located on the under surfaces of said parts,so that said frame ZIJ'and head 2| may swing downwardly into the cabinetH). Theframe 20 may be made of two pieces hinged together at 22, asshown in Figs. 2 and 5, to facilitate storing of the frame in thecabinet ID.

A lid 23, rectangular in shape and large enough to cover the opening [9in the top 14, is hingedly connected to the top. inwardly of its endmargin, by hinges 24. Said lid 23 is as wide as the space between themembers l5, [5 of the top. The lid 23 is connected to the top member Itby a link 25, one end of said link 25 being pivotally' secured at 26 tothe rear edge of the lid 23'and the other end being provided with a pin21 adapted to be slidably retained in a slot 28 grooved portion, withthe'head of the pin 21" within the slot 28. When the lid 23 is manuallymoved to open position, as in Figs. 1, 2, 3 and 6, the link 25 and topsection l6 are actuated 2 and moved from the position shown in 8 to thatof Fig. 6. Fig. '7 shows an intermediate position," In order'to'permitthe lid 23 to lie in the same plane as the top I4, thetopsection l6, f

is thus'moved out of the recess between the parts [5, to a positionbeneath the lid 23 as shown g in Fig. 6, and said recess is occupied bythe hinged end of the lid'23, When the lid is manually moved to closedposition, the link 25 and top section l6 move with the lid the pin2|{sliding in slot 28, to' the position shown in Fi'g'f'8. a

V the lid 23 at as.

In the preferred embodiment of my invention shownin the drawings, thehead frame 2| and, lifting brace 30, the latter connected throughpivoted arms 3!, 3| and 32, 32, to the frame 2| and back wall 34,respectively, are connected through a chain 35 or other suitable meanswith a pulley '31 on a stub shaft 38 fixed to the rear wall 34 When thelid is moved from closed a position the head frame 20 and liftingbraceare automatically lifted from the position shown in Fig, 4 to that shownin Figs. 3 and 5. The 7 moving of the lid to closedi position permits{the chain to move downwardly over the pulley 3'! and the head frame 20andassociated parts to drop into the cabinet l0.

By the construction disclosed, the lid 23 is properly supported when inopen position by 'restingat one end on the cabinet l0, without having anintermediate or raised portion between the top Hand lid23,
